“…These five were: 1) A lamina that separates our revised dorsal mesopallium from the intercalated hyperpallium, previously named in some studies as lamina frontalis suprema [abbreviated LFM in the 2004[abbreviated LFM in the -2005, which we propose to rename as lamina mesopallium dorsalis (LMD); 2) A lamina located between our revised dorsal mesopallium and ventral mesopallium, which has been unintentionally given various names in the literature due to the aforementioned problems, including lamina frontalis superior (LFS) in the revised nomenclature Table 2). Instead, as noted in Wild and Williams (1999), the number of laminae we found from the dorsal telencephalic surface to the nidopallium are three, all separating different parts of our revised mesopallium and adjacent brain subdivisions. For this reason, we believe including the term mesopallium in their names as LMD, LMI, and LMV is appropriate ( Fig.…”

The patterns of constitutively expressed genes revealed a partial mirror image organization of three major cell populations that wrap above, around, and below the ventricle and adjacent lamina through the mesopallium. The patterns of behaviorally regulated genes revealed functional columns of activation across boundaries of these cell populations, reminiscent of columns through layers of the mammalian cortex. The avian functionally regulated columns were of two types: those above the ventricle and associated mesopallial lamina, formed by our revised dorsal mesopallium, hyperpallium, and intercalated hyperpallium; and those below the ventricle, formed by our revised ventral mesopallium, nidopallium, and intercalated nidopallium. Based on these findings and known connectivity, we propose that the avian pallium has four major cell populations similar to those in mammalian cortex and some parts of the amygdala: 1) a primary sensory input population (intercalated pallium); 2) a secondary intrapallial population (nidopallium/hyperpallium); 3) a tertiary intrapallial population (mesopallium); and 4) a quaternary output population (the arcopallium). Each population contributes portions to columns that control different sensory or motor systems. We suggest that this organization of cell groups forms by expansion of contiguous developmental cell domains that wrap around the lateral ventricle and its extension through the middle of the mesopallium. We believe that the position of the lateral ventricle and its associated mesopallium lamina has resulted in a conceptual barrier to recognizing related cell groups across its border, thereby confounding our understanding of homologies with mammals.

“…Most of the auditory input from CM to NIf originates from a subdivision of CM, known as nucleus avalanche (Av), that is defined by its strong reciprocal connections with both NIf and HVC (Nottebohm et al, 1982; Akutagawa and Konishi, 2010). NIf also receives a likely somatosensory input from the rostral Wulst (Wild and Williams, 1999). Finally, NIf may receive multisensory (somatosensory, visual and auditory) input from Uva, which also projects directly to HVC (Bischof and Engelage, 1985; Wild, 1994; Coleman et al, 2007; Mendez et al, 2009).…”

Communication between auditory and vocal motor nuclei is essential for vocal learning. In songbirds, the nucleus interfacialis of the nidopallium (NIf) is part of a sensorimotor loop, along with auditory nucleus avalanche (Av) and song system nucleus HVC, that links the auditory and song systems. Most of the auditory information comes through this sensorimotor loop, with the projection from NIf to HVC representing the largest single source of auditory information to the song system. In addition to providing the majority of HVC’s auditory input, NIf is also the primary driver of spontaneous activity and premotor-like bursting during sleep in HVC. Like HVC and RA, two nuclei critical for song learning and production, NIf exhibits behavioral-state dependent auditory responses and strong motor bursts that precede song output. NIf also exhibits extended periods of fast gamma oscillations following vocal production. Based on the converging evidence from studies of physiology and functional connectivity it would be reasonable to expect NIf to play an important role in the learning, maintenance, and production of song. Surprisingly, however, lesions of NIf in adult zebra finches have no effect on song production or maintenance. Only the plastic song produced by juvenile zebra finches during the sensorimotor phase of song learning is affected by NIf lesions. In this review, we carefully examine what is known about NIf at the anatomical, physiological, and behavioral levels. We reexamine conclusions drawn from previous studies in the light of our current understanding of the song system, and establish what can be said with certainty about NIf’s involvement in song learning, maintenance, and production. Finally, we review recent theories of song learning integrating possible roles for NIf within these frameworks and suggest possible parallels between NIf and sensorimotor areas that form part of the neural circuitry for speech processing in humans.

This communication presents a concise overview of reports in the literature concerning the occurrence of extratelencephalic fibre tracts in birds and the comparability of these tracts with the mammalian pyramidal tract. Emphasis is on the intratelencephahc organization, in particular that of the intratelencephalic sensorimotor circuits processing information from all important types of sense organs. It is suggested that two descending tracts, the occipitomesencephalic tract and the basal tractus superficialis medialis in birds have the same role in guiding behaviour as the pyramidal pathway in mammals. However, the differences in origin, trajectory and targets suggest that two independent systems may have developed in birds. One of these, the basal tractus superficiahs medialis, represents the homologue of the pyramidal tract. It is suggested that the occipitomesencephalic tract is a specific feature of birds that has developed during the evolution from the early dinosaurs to birds. This suggestion follows from recent observations on the evolution of birds.
